I had the need to store extra Creality K1 Printer build plates (four). I looked and didn't find one I liked so I designed my own in Fusion360. I split the model into two half sections to make it easier to print on smaller size build plates. The connecting blocks have a 1 mm channel on the top side for additional super glue when connecting the halves. I printed the pictured models using Creality Hyper PLA.
The author marked this model as their own original creation.
